Coinkee looks really nice. Is there any topics on bitcointalk for coinkee?

Not yet, it's fairly new. I will publish a deterministic build in the near future so people can check the source code or create their own. All I've done is create a custom Ubuntu LiveCD/USB combo with a pre-installed light version of bitaddress.org. It's nice and clean and I use it all the time to generate paper wallets for all kinds of use cases. What's great is that the private keys never touch the internet until I choose to "cash them in" and when I do that I transfer the change to a new cold/paper wallet. Mycelium android wallet is good for that.
